`Applicationriled November 29, 192.0. hs eriallo. 426,963.

T o all whom t may concern:

Bc it known that I, JAMEs M. ALLEN, a citizen of the United States, and resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements lin Storage Batteries, of which the following is a specification containing a full, clear, and exact description, A reference drawings, forming a part hereof.

This invention relates to improvements in storage batteries and has for -its primary 'object the construction of a storage battery wherein the positive plates are connected in pairs so as to prevent their buckling or zwarping.

A further object is to construct a storage battery wherein the positive plates are connected together in units of pairs with braces between the vertical edges. of the (onnected pairs so that the plates can not buckle or warp, when the battery is subjected to extremely hard usage and a negative plate inserted between the: plates composing each of the units and between adjacent units.

In the`drawings:

Fig. 1 is a perspective view of a pair of positivev pl tes showing the manner of connecting t e same.

Fig., 2 is a perspective view of one of the negative plates.

. Fig. 3 is a top plan view of several units showing the manner of assembling the positive and negative plates within the batter Iyn the construction= of my ldevice I employ the positive plates 4. These plates are provided with a grid which is filled and 7 are provided with a plurality ot tapered.- recesses 8 in which spacing bars 9 are placed. These baril, after being placed in the recesses, are hurried or welded `therein, vthus uniting the two plates into a unit, which is reenforced along its vertical edges so that warping or buckling will be prevented. The upper edge of the plates is provided with an extension .10, which is for the purpose lof securing the plates to a crows foot. The negative plate 11 is also provided with a grid in which active material 12l` is secured. Along the vertical edges of the negative plate, are strips 13.

being hadA to the accompanyingpositive plates with active.material 5, the vertical edges 6.

These strips are preferably U-shaped and of hard rubber, although they may be made of any desired shape and any acidLresisting non-conductor. The upper edge of the negative plate 11 is provided with'an extension 14 for securing it to a crows foot.

The strips 13 are designed to'. prevent the vertical edges of the negative plates Vfrom coming in contact with .t e bars 9 and thus cause a short circuit.

n. assembling the plates for battery uses, a negative plate is inserted between a unit of positive plates, as shown in Fig. 3', the strips 13 acting as a separator for the vertical edges of the plate. The facesv of the negative' and are separated from each other by means of separators 15. rIhese separators are of any desired construction. Between the adjoiningpositive units is inserted a negative plate, which is also separated from the. positive units by means of the separators 15. These negative plates, which are inserted between the adjoining positive units, may or may not be provided with the` strips manufacturer whether to use the same or not. vWhile I have shown the positive units connected by two Abars on each of the vertical sides, I may also, if desired, bind the plates together on thebottom, or

4use more bars on the vertical sides. In case the plates arel bound on the bottom, it will 13, it being optional with the -be necessary also to putl a strip 13 along preferred construction, however, is that shown in Fig. 1. By binding the positive.

plates together in pairs it is practically 1mpossible for them to warp or buckle since in. order to must bend in the same direction, and in order to do this must also bend the negative plate, as well-as'bend the bars 9, and

it will be practically impossible to put sufficient strain on the battery to cause warping or buckling to take place.

Having fully described my invention, what I claim is: Y

1. A storage battery comprising a plurality of positive and negative plates, a plurality of bars for connecting the positive plates together in pairs along their vertical edges, strips extending along the vertical edges of the negative plates for preventing contact with the bars when the negative d o so both plates of the unit plates are placed in position, and a plurality of separators interposed between the positive and negativ-e plates. v l

2. A storage battery comprising a plurality of positive and negative plates arranged alternately, a plurality of horizontally extending bars for vconn'eetinggthe Vertical edges of the positive plates, so as Lamers? to connect them together in pairs, insulating means carried by the Vertical edges of l@ the negative plates for preventing Contact with said bars, and separators' .interposed between the positive and negative plates.

In testimony whereof, I have signed my name to this specification. A

JAMES M. ALLEN.
